Product Overview

The liquid CO₂ high-pressure plunger pump is a versatile, high-pressure pump specifically designed for the transfer of liquid carbon dioxide in various industrial processes. The pump is suitable for applications such as pressure testing, cleaning, membrane-based hydrogen recovery, and methanol-water washing. It offers multiple installation options—horizontal, vertical, fixed, or mobile—allowing adaptability to different work environments. With adjustable pressure and flow capabilities, the pump provides precise liquid delivery across a wide range of operating conditions.

Working Principle

The pump operates on a plunger reciprocating mechanism. Liquid CO₂ is pressurized and delivered as the plunger moves back and forth within the pump cylinder. Flow rate can be flexibly adjusted via electromagnetic speed control, variable frequency drive, or by changing the plunger diameter. System pressure is controlled through a safety pressure valve to ensure safe and stable operation under varying conditions. Pump body materials include corrosion-resistant alloy steel, martensitic or austenitic stainless steel (316, 316L, and duplex steels), ensuring durability and safety for low-temperature liquid and chemical media transfer.
